CN3791 Li-ion Battery Charger IC With Photovoltaic Cell MPPT Function

 CN3791- 4A Standalone Li-ion Battery Charger IC With Photovoltaic Cell MPPT Function - SSOP 10 Pin

The CN3791 is a PWM switch-mode lithium ion battery charger controller that can be powered by photovoltaic cell with maximum power point tracking function with few external components.

The CN3791 is specially designed for charging lithium ion batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage can be fixed at 4.2V with ±1% accuracy. The constant charge current is programmable with a single current sense resistor.

Deeply discharged batteries are automatically trickle charged at 17.5% of the full-scale current until the cell voltage exceeds 66.5% of constant voltage. The charge cycle is terminated once the charge current drops to 16% of full-scale current, and a new charge cycle automatically restarts if the battery voltage falls below 95.5% of regulation voltage. CN3791 will automatically enter sleep mode when input voltage is lower than battery voltage.

Other features include under voltage lockout, battery over voltage protection, status indication. CN3791 is available in a space-saving 10-pin SSOP package.
